Testing alternate way of implementing spoiler \require{action} \require{enclose} \toggle{ x\cdot 0 = 0\quad\enclose{roundedbox}{\text{ Click this for derivation }} }{ \begin{array}{rll} x\cdot 0 &= \mathtip{x\cdot 0 + 0}{0 \text{ is additive identity}} \\ &= \mathtip{x\cdot 0 + (x\cdot 0 + -(x\cdot 0))}{ -(x\cdot 0) \text{ is additive inverse ... 21 You can begin every line with >! and end it with two spaces. 18 There are three approaches for line breaks. As pointed out in the comments, Approaches 2 and 3 produce the same HTML output when rendered on the page. Approach 1: Press "Enter" twice Output: Hi Bye Code: Hi Bye Approach 2: Two spaces at end of line Output: Hi Bye Code: Hi Bye There are two spaces after "Hi." That is, the text looks like: Hi&... 14 A problem is that it is not a semantically correct use. At the moment the formatting used by SE on this site for block-quotes is such that optically its usage for emphasis makes sense. Yet, this could change at any point in time. Moreover, already now I feel it is not really the case on the mobile site. In addition, imagine some machine reads the site to ... 13 Simple solution: don't abuse MathJax to colour your text. 12 The commands \lbrack and \rbrack are macros that produce [ and ] respectively, and MathJax has no problem when you use them instead of the symbols - see the comment below, which was produced by For any a,b\in \lbrack 0,x): a\vee b exists. Namely, a\vee b=\max\{a,b\}. You might be asking about when directed sets are [complete](http://en.wikipedia.org/... 11 Use mathjax for mathematics, not for text formatting. The mathjax italics happen because mathjax thinks "abcde" is just a string of variables. 10 Use Markdown's inline link syntax, an example of which is shown when you click the "help" link under "Add Comment". [link text](http://link-uri.com) This works in answers as well. 10 Thinking about it, I also realize that we could \Large\text{use LaTeX} in ways that are \Huge\text{still of questionable merit}, but which fit inline. Note that we can't {\fontsize{3cm}{1em}\selectfont use an arbitrary fontsize}. But then again, some might ask \Tiny\text{why we would do this at all.} 9 I don't there's been any recent change; this is how things have always worked. To get a single line break, put two spaces at the end of the line - for example, **Theorem** adsfdf *proof*: asdfdsaf produces Theorem adsfdf proof: asdfdsaf 9 For F.Zer \begin{align} f(x:xs) &= \sum_{i:\ 0 \leq i < \#(x:xs)} (x:xs).i * (i + 1)\\ &=\sum_{i:\ i =0} (x:xs).i * (i + 1)+\sum_{i:\ 1\le i<\#xs+1}(x:xs).i * (i + 1)\\ &=x + \sum_{i:\ 1 \leq i \le \#xs} xs.(i-1) * (i + 1)\\ &=x + \sum_{j:\ 0 \leq j < \#xs} xs.j * (j + 2)\quad\quad(\text{Here }j=i-1\text{ and }i\text{ is replaced ... 9 I've gone an updated the CSS for spoilers - there was something overriding the spoiler CSS in this instance. With you in the next build (rev. 2017.3.14.*) 8 You can quote by simply using quotation marks. You can write a link in a post or comment like [this](url here), for example google link. 8 When I look at the specific comment you linked to, I think that the only problems is that you did not include http:// at the beginning of the link. You wrote this: [ArtOfProblemSolving forum](www.artofproblemsolving.com/Forum/viewtopic.php?p=3542095&sid=61650444d5d??5e56fb5c71a50982e4912#p3542095) which does not work: ArtOfProblemSolving forum. If you ... 7 I suppose if you really wanted to Then you could vary it up by abusing headers But this hurts my sensibilities 7 This answer to a similar question (as linked to in the comments by Martin Sleziak) suggests the hack of\tag*{$\blacksquare$}$$, which looks like the following: ...and the proof is complete. \tag*{\blacksquare} Frustratingly, it takes a new line. But I do not think this is an issue, as issues go! 7 The former is a block quote the later is a spoiler. There is also preformatted text, which might qualify. It looks like this. This is preformatted text. It is especially useful for code. You can get it by indenting the text with four spaces. A feature or issue with this is that it will not break you lines, but instead will add a slider. Like this. This ... 6 Move your mouse around each symbol to know which font was used:$$\require{action} \overset{\rlap{\overset{\,{\rlap{\overset{\overset{\overset{\color{red}{\rlap{\color{\green}{\,\,\star}}{\Rule{1em}{0.5em}{0.25em}}}}{}}{}}{}}{\Huge|}}}{}}{\Rule{0.5em}{0.25em}{0.05em}}}{\overset{\Rule{2em}{0.05em}{0.05em}}{\overset{\Rule{5em}{0.05em}{0.05em}}{\overset{\Rule{...

The best thing I can think of     is to end the preceding line with two whitespaces        (which creates a single line break)           and copy-paste several &nbsp; at the beginning of next line. (Turns out this is same method as in the link Martin posted.)

It seems to be that if you do >! at the beginning of a line, you get that. You could have found that out by clicking edit post and looking at the source. for example.

Line-breaks and paragraphs in comments are not supported. The shift-enter is intended only to affect the situation while you edit. It is possible to work around this restriction via using MathJax. But doinng so is discouraged. If you need some visual separation, use some symbols for example // like this: This is one important remark I want to make and ...

You can mimic the indentation by just adding a space in front of the new paragraph, like so: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent at sem interdum sem aliquet porttitor. Ut eleifend ligula at tristique fermentum. Nulla facilisi. Curabitur lacinia ligula sed sem pulvinar ultrices. Phasellus id bibendum mi. Nulla sodales quam a ...
